1SYN372342R8600

ABB 1SYN372342R8600 (SDA-60) is a fully automatic Star-Delta motor starter designed for controlled starting of large three-phase induction motors. ABB identifies this exact catalogue number as the SDA-60, 400–415 V coil variant in its Star-Delta starter range. The starter is intended for 60 HP motors at 415 V AC, equivalent to approximately 45 kW in current product listings. During startup, the motor windings are initially connected in star configuration, which reduces starting current compared with Direct-On-Line starting. After the preset transition period, the starter automatically changes to delta configuration for normal motor operation. Typical applications include large pumps, compressors, blowers, fans, conveyors, HVAC systems, processing machinery and industrial motor-control panels where reduced starting current is required.
